I am not sure if endometriosis comes under the umbrella of chronic pain or not, as the pain is intermittent, usually around period time or ovulation. But I’ve dealt with that for 24 years. It started when I was 12 and I wasn’t diagnosed until I was 28 or 29. I have exhausted the treatments and I am down to surgeries once every 5-10 years or a hysterectomy, which doesn’t 100% sort it either.
I remember saying to someone that the pain wasn’t actually that bad anymore (I used to throw up from the pain as a teen and sometimes pass out) that person said, “Sweetie, the pain is the same, you’ve gotten used to it.” She was right, I don’t feel it as much anymore, I still feel the nausea and the fatigue. That might sound great but pain has a function. Because of this learnt higher pain threshold I didn’t feel any pain from the DVT I had in my leg until it stretched from my belly button to my calf. I could have easily lost my leg, not to mention my life.
